You are provided a string $S$. Your task is to determine whether the provided string is a valid IP address.

A valid IP address is determined based on the following rules:

1. The IP address must exactly contain four non-empty parts that are separated by three dots. For example, $255.255 .255 .255$.
2. The decimal value of each part of the IP address should not exceed $255$ and must not be less than zero.

Input format

The first and only line of the input contains the string $S$.

Note

• The string must contain only numbers and the $.$ symbol of the ASCII character set only.
• All IP addresses must be in the decimal format, that is, base 10 notation only.

Output format

If the provided IP address is valid, then print $YES$. Otherwise, print $NO$.

Note: Print the output in a single line.

Constraints
